A double-layer porous dust barrier based on the elastic expansion of rice leaf surface

Abstract

The invention discloses a double-layer multi-hole dust-retention barrier based on the elastic splaying of leaf surfaces of rice. A rigid multi-hole dust-retention net with hollow round meshes and a limiting hole is arranged on the outer side of the barrier, a flexible super-hydrophobic cleaning net with four-leaf solid meshes and a limiting hole is arranged on the inner side of the barrier, the hollow round meshes, four-leaf solid meshes and the limiting holes are formed in a one-to-one correspondence manner, central points in pairs coincide, and net pieces on the inner and outer sides are limited by limiting-fixing components and are fixedly connected. The meshes of the flexible super-hydrophobic cleaning net of the double-layer multi-hole dust-retention barrier are of a four-leaf solid mesh design, the passive adjustment of the porosity is realized by virtue of elastic splaying of leaves, and the size of incoming wind resistance can be effectively adjusted, so that the contact area between the meshes and fine particulate matters is increased; and the barrier is woven by virtue of high-strength polyester fiber silk yarns, the surface of the barrier is processed by virtue of a Nano-Sphere coating technique, a rice-leaf-similar super-hydrophobic surface is formed, and the self-cleaning property of the surface of the barrier is utilized, so that the fine particulate matters can be effectively adsorbed and captured, and the dust retention effect is improved.

Description

technical field [0001] The invention relates to a double-layer porous dust-retaining barrier, in particular to a double-layer porous dust-retaining barrier based on the elastic expansion of rice leaf surfaces, and belongs to the technical field of atmospheric environmental protection implementation. Background technique [0002] Existing porous dust barriers are mainly used in industrial sites such as coal mines, ports, and raw material factories. In terms of agricultural production, especially in places with fugitive pollution sources, many fine particles cannot be captured and removed well. This will cause a series of environmental pollution problems and health problems, such as PM 1 , PM 2.5 , PM 10 (Particulates with aerodynamic diameters less than or equal to 10 μm, 2.5 μm and 1 μm respectively) and other fine particles; the existing porous dust barrier, with a fixed porosity, can only reduce the incoming wind speed, and cannot truly achieve the adsorption of fine par...

[0002] Existing porous dust barriers are mainly used in industrial sites such as coal mines, ports, and raw material factories. In terms of agricultural production, especially in places with fugitive pollution sources, many fine particles cannot be captured and removed well. This will cause a series of environmental pollution problems and health problems, such as PM 1 , PM 2.5 , PM 10 (Particulates with aerodynamic diameters less than or equal to 10 μm, 2.5 μm and 1 μm respectively) and other fine particles; the existing porous dust barrier, with a fixed porosity, can only reduce the incoming wind speed, and cannot truly achieve the adsorption of fine particles and capture, and the mesh is inconvenient to clean, the reuse rate is low, and the production cost is high, which will cause the problem of waste of resources
